That means that the current OFED 3.5 ib_srp driver can't work on RHEL 6.x since the RHEL 6.x SCSI LLD API is different from the Linux kernel 3.2 SCSI LLD API. A quote from the Linux kernel 3.2 include file <scsi/scsi_host.h>: int (* queuecommand)(struct Scsi_Host *, struct scsi_cmnd *); A quote from the RHEL 6.3 include file <scsi/scsi_host.h>: /* * [ ... ] * NOTE: The 'lockless' flag in the scsi_host_template indicates * whether the host_lock should be held before calling this * routine. Also, the lockless queuecommand, as implemented * upstream has a different signature. */ int (* queuecommand)(struct scsi_cmnd *, void (*done)(struct scsi_cmnd *)); [ ... ] /* * True if we are calling queuecommand without the * host_lock held. LLDs may want to do this for * performance reasons. */ unsigned lockless:1; Bart. On 09/09/12 04:36, Rupert Dance wrote: > Hello, > > UNH-IOL has verified the same problem using SL 6.2 and SL 6.3.
